在我國(guo)的(de)(de)(de)鋼(gang)管(guan)(guan)制造標準中，有結構用(yong)(yong)(yong)(yong)鋼(gang)管(guan)(guan)和流(liu)(liu)體(ti)輸送(song)用(yong)(yong)(yong)(yong)鋼(gang)管(guan)(guan)之(zhi)分(fen)。結構用(yong)(yong)(yong)(yong)鋼(gang)管(guan)(guan)主要(yao)用(yong)(yong)(yong)(yong)于一般金屬結構如橋、梁、鋼(gang)構架(jia)等(deng)，它(ta)只要(yao)求(qiu)保(bao)證(zheng)(zheng)強度與(yu)剛度，而對鋼(gang)管(guan)(guan)的(de)(de)(de)嚴(yan)密性不作要(yao)求(qiu)。流(liu)(liu)體(ti)輸送(song)用(yong)(yong)(yong)(yong)鋼(gang)管(guan)(guan)：主要(yao)用(yong)(yong)(yong)(yong)于帶有壓力(li)的(de)(de)(de)流(liu)(liu)體(ti)輸送(song)，它(ta)除了要(yao)保(bao)證(zheng)(zheng)有符合(he)相應要(yao)求(qiu)的(de)(de)(de)強度與(yu)剛度外，還要(yao)求(qiu)保(bao)證(zheng)(zheng)密閉性，即在出廠前要(yao)求(qiu)逐根(gen)進(jin)行水壓試驗(yan)。對壓力(li)管(guan)(guan)道來說(shuo)，它(ta)輸送(song)的(de)(de)(de)介質(zhi)常常是(shi)易燃、易爆、有毒、有溫度、有壓力(li)的(de)(de)(de)介質(zhi)，故應選用(yong)(yong)(yong)(yong)流(liu)(liu)體(ti)輸送(song)用(yong)(yong)(yong)(yong)鋼(gang)管(guan)(guan)。在實(shi)際的(de)(de)(de)工(gong)程設計、采購和施工(gong)中，發現(xian)有用(yong)(yong)(yong)(yong)結構用(yong)(yong)(yong)(yong)鋼(gang)管(guan)(guan)代替流(liu)(liu)體(ti)輸送(song)用(yong)(yong)(yong)(yong)鋼(gang)管(guan)(guan)的(de)(de)(de)現(xian)象，這是(shi)絕對禁止的(de)(de)(de)。
